The U.S. Supreme Court issued a per curiam (published in the name of the Court rather than specific judges) opinion today reversing the Texas Court of Criminal Appeals (TCCA) and finding that Bobby Moore is a person with intellectual disability and his execution is prohibited by the Eighth Amendment to the U.S. Constitution’s ban on cruel and unusual punishment.

“The Arc applauds the Court’s decision today which again embraces the standards-based approach in determining intellectual disability for which The Arc has long advocated. When it comes to matters of life and death, there is simply no room for courts to ground their determinations of intellectual disability in outmoded and baseless stereotypes. The Arc is grateful to the Court for taking a strong stance today to ensure that its precedent on this issue is properly interpreted in jurisdictions around the country,” said Marty Ford, Senior Advisor, The Arc.

This is the second time Mr. Moore has sought relief from the Supreme Court and won. In 2017, in the same case, the Court rejected Texas’ use of stereotypical and outdated factors—rather than well-established clinical standards—to determine intellectual disability in death penalty cases on the grounds that they “create an unacceptable risk that persons with intellectual disability will be executed.” The Court then sent the case back to the TCCA to determine whether Mr. Moore had intellectual disability in light of its opinion. Following the TCCA’s 2018 finding that he did not have intellectual disability, Mr. Moore again petitioned for Supreme Court review. Notably, the prosecutor in Mr. Moore’s case—the district attorney of Harris County—filed a brief in support of Mr. Moore noting that, in light of the Supreme Court’s 2017 opinion, Mr. Moore is an individual with intellectual disability who cannot be executed.

In its opinion today, the Court noted that “Moore has shown he is a person with intellectual disability” and that the most recent TCCA opinion must be reversed because it continued to exhibit “lay stereotypes” of people with intellectual disability despite the Supreme Court’s clear instruction to rely on well-established clinical standards instead. Chief Justice Roberts, in a concurring opinion, noted that while he still believes the original Moore opinion “lacked clarity,” “it is easy to see that the Texas Court of Criminal Appeals misapplied it here…the court repeated the same errors that this Court previously condemned…” Justice Alito, joined by Justices Thomas and Gorsuch, dissented, noting that “The error in this litigation was not the state court’s decision on remand but our own failure to provide a coherent rule of decision in Moore.”

The Arc filed amicus briefs on Mr. Moore’s behalf when he first went before the Supreme Court in 2016 and again when his case was remanded to the TCCA in 2017.

In its 2002 decision in Atkins v. Virginia, the U.S. Supreme Court recognized the special risk of wrongful execution faced by persons with intellectual disability and banned their execution as cruel and unusual punishment under the Eighth Amendment. Subsequently, in Hall v. Florida (2014), the Court rejected an arbitrary cutoff for IQ scores in making the intellectual disability determination and emphasized the importance of courts consulting clinical standards in their analysis. The Court’s 2017 and 2019 decisions in Moore v. Texas have strengthened this precedent by emphasizing the need to rely on well-established clinical standards—rather than stereotypes—in making intellectual disability determinations in death penalty cases.

The Arc has deep sympathy for the family and friends of the victim in this case, and we supported appropriate punishment of all responsible parties. The Arc did not seek to eliminate punishment of Mr. Moore or others with disabilities, but rather, to ensure that justice is served and the rights of all parties are protected. The Arc is committed to seeking lawful outcomes for people with ID and will continue working to ensure that the U.S. Supreme Court rulings on this issue are abided by in jurisdictions across the country.
